Hi,
Recently I tackled the issue of editors and keybindings in tmux. This
has been addressed on the mailing list a couple times before [0][1], and
has spawned a bunch of SO posts, etc. It would be really nice if
solutions were in the FAQ.
Most of what I think should be added was already written by Chris
Johnsen: on here about emacs [1], and on SO about vim [3].
I think I found a simpler (and elispy) alternative solution for emacs
based on what I found on the emacs help mailing list [2]. I try to
explain all the details for the below snippet in its comments.
---
# For each new Emacs frame, a function is called to initialize
# term-specific things. The function `terminal-init-screen' loads the
# xterm library just to figure out 88 or 256 colors; it does not map
# the xterm-specific keys.
#
# This is an `advice' to augment `terminal-init-screen', which one can
# add to `~/.emacs/init.el' to get xterm keys in Emacs & tmux, when
# `xterm-keys' is set to `on' in tmux.
(defadvice terminal-init-screen
;; The advice is named `tmux', and is run before
;; `terminal-init-screen' runs.
(before tmux activate)
;; Docstring. This describes the advice and is made available inside
;; emacs; e.g. when doing C-h f terminal-init-screen RET
"Apply xterm keymap, allowing use of keys passed through tmux."
;; This is the elisp code that is run before `terminal-init-screen'.
(if (getenv "TMUX")
(let ((map (copy-keymap xterm-function-map)))
(set-keymap-parent map (keymap-parent input-decode-map))
(set-keymap-parent input-decode-map map))))
